As per my knowledge JMP is better in case of discrete choice experiment design without prior knowledge. JMP-11 is very user friendly and straight forward.

Hi

Please see: www.statease.com/dx9.html

JMP and expert choice are good i used both of them and they are so easy to use

Sawtooth or Ngene might help

Dear  Shubhajit Sadhukhan 

In your research, for the experimental design and statistical analysis, you can use “Design-Expert” software. I explain that step by step in my article. You can see my new publication in below link.

Also, you can use "Taguchi method" for your research purpose.

I hope my articles; help you in your research field.

Good Luck

You can use taguchi method in minitab software.

you can use "BIOGEME" software, too

Dear Hashem

Is "BIOGEME" is a freeware? Is it code based or having user friendly interface?

Which (free) software is suitbale to design choice experiments with Mac?

Sawtooth or NGENE

@Jacob Kazungu  Thank you. However, how to get these software? 

NGENE

R has a package "support.CEs" that can also design discrete choice experiments. Here is the reference: Aizaki, Hideo. "Basic functions for supporting an implementation of choice experiments in R." Journal of statistical software 50 (2012): 1-24.

Here is the link: https://www.jstatsoft.org/article/view/v050c02

Please note I had to install all the dependent packages manually. Otherwise, it seems to have worked fine so far.

Ngene has been used in many academic publications. I am also planning to use it for my Phd research though it is bit expensive and I didn't find any mac version of the software. Please download and read the manual from "http://www.choice-metrics.com/NgeneManual120.pdf". Hope this helps.

stata is better for choice experiment and estimate logit model

You can use Minitab software.
